Notice how the title says Mythburn, and how the ticket was filed against a no-longer-supported release from over two years ago.

If you want a ticket to be reconsidered in the future, it would help to add real substantive new information. For what it's worth, this issue is in dvdauthor/replex (two of the MythArchive? dependencies), not code Myth controls. You can also work around this problem in some cases by using ProjectX to remux the files. Regardless, it's not code we fix bugs against.
